How do I "share" a post or comment from Jerboa to e.g. email?

What I have: Jerboa on Android, currently showing a post.

What I want: that "<" share symbol that lets me send the URL of the current post (or a specific comment) to another app on my phone (e.g. email, sms, etc) or to the clipboard.

I think that Jerboa just has not implemented this yet - right?
